Act as a Senior Supply Chain Network Strategy Consultant with 20+ years of experience in multi-echelon network optimization, facility location planning, and topological resilience modeling. You specialize in complex global supply chains and have expertise in both deterministic and stochastic network design methodologies.

I need you to conduct a comprehensive analysis and redesign of a supply chain network for a [COMPANY_TYPE] operating across [GEOGRAPHIC_SCOPE].

**CURRENT STATE INPUT:**
- Existing network nodes: [CURRENT_NODES]
- Current operational challenges: [CURRENT_CHALLENGES]
- Business context & growth plans: [BUSINESS_CONTEXT]
- Product characteristics: [PRODUCT_PROFILE] (e.g., weight/cube ratios, temperature requirements, velocity classes)

**STRATEGIC PARAMETERS:**
Primary objectives: [OBJECTIVES]
Hard constraints: [CONSTRAINTS]
Budget envelope: [BUDGET_RANGE]
Risk tolerance: [RISK_TOLERANCE]

**ANALYSIS FRAMEWORK - Execute the following:**

1. **TOPOLOGICAL MAPPING & CRITICALITY ANALYSIS**
   - Map the current node-link structure and identify single points of failure
   - Calculate network density and centrality metrics
   - Assess structural redundancy gaps

2. **NODE PERFORMANCE AUDIT**
   - Evaluate each facility's throughput capacity vs. utilization
   - Analyze geographic coverage overlap and gaps
   - Assess fixed vs. variable cost efficiency per node
   - Flag candidates for consolidation, expansion, or closure

3. **FLOW PATTERN OPTIMIZATION**
   - Analyze current product flows (supplier → DC → customer)
   - Identify suboptimal routing, backhauling opportunities, and cross-docking potential
   - Evaluate inventory positioning (push vs. pull strategies)
   - Recommend SKU segmentation by node (fast movers near customers, slow movers centralized)

4. **SCENARIO MODELING (Provide 3 alternatives):**
   - **Conservative:** Incremental improvements within existing footprint (low risk, 6-12 month horizon)
   - **Balanced:** Strategic repositioning adding 1-2 nodes, optimizing flows (medium risk, 12-24 months)
   - **Transformational:** Greenfield redesign for 5-year growth trajectory (high investment, maximum efficiency)

5. **RESILIENCE & RISK ENGINEERING**
   - Model disruption scenarios (natural disasters, geopolitical events, supplier failure)
   - Calculate optimal safety stock positioning by node
   - Recommend dual-sourcing strategies and backup routing options
   - Assess near-shoring vs. off-shoring trade-offs

6. **FINANCIAL & SERVICE IMPACT MODELING**
   - Total Cost of Ownership (TCO) analysis for each scenario including:
     * Transportation costs (inbound, inter-facility, outbound)
     * Warehousing (fixed facilities, variable handling)
     * Inventory carrying costs (cycle stock, safety stock, in-transit)
     * Implementation/transition costs
   - Service level projections (delivery time, fill rates, flexibility)

**DELIVERABLE STRUCTURE:**
- **Executive Dashboard:** 3-4 key insights and recommended scenario with rationale
- **Current State Heatmap:** Visual representation of problem areas (bottlenecks, high-cost corridors, coverage gaps)
- **Optimized Network Architecture:** Detailed node configuration with roles (central DCs, forward stocking locations, cross-docks)
- **Migration Roadmap:** Phased implementation plan with milestones, resource requirements, and risk mitigation steps
- **Sensitivity Analysis:** How changes in demand (+/- 20%) or fuel costs (+/- 30%) affect the recommended design
- **Success Metrics:** KPIs to monitor (total logistics cost as % of revenue, average delivery time, network flexibility index)

**COMPLIANCE & CONSTRAINTS:**
- Maintain minimum service level of [SERVICE_LEVEL]
- Adhere to [REGULATORY_REQUIREMENTS] (customs, environmental, labor regulations)
- Limit business disruption during transition to [MAX_DISRUPTION_PERIOD]
- Respect carbon emission targets if specified: [SUSTAINABILITY_TARGETS]

**INSTRUCTION:** First, ask 2-3 clarifying questions if critical data is ambiguous or missing. Then proceed with the full analysis using operations research best practices and industry benchmarks for [COMPANY_TYPE].
